Birds Nested Alongside Dinosaurs in the Arctic: Fossil Find Pushes Polar Nesting Record Back by 25 Million Years
- Researchers discovered over 50 bird fossils dated to about 73 million years ago in northern Alaska's Prince Creek Formation, revealing Arctic nesting in the Cretaceous.
- This discovery pushes back the earliest evidence of bird reproduction in Arctic regions by about 25 million years, from roughly 47 million years ago—long after the extinction of non-avian dinosaurs—to nearly 73 million years ago during the Cretaceous period.
- The fossils include bones from adult and young birds resembling modern shorebirds and waterfowl, indicating they nested and raised offspring alongside dinosaurs in the polar environment.
- Lauren Wilson and Pat Druckenmiller highlighted that discovering bird fossils from the Cretaceous period is extremely uncommon, and this finding extends the known timeline of birds nesting in Arctic areas by approximately 25 to 30 million years.
- The evidence implies that Arctic bird communities existed during the age of dinosaurs, suggesting that such high-latitude ecosystems have long been integral to Earth's history.

Birds have been nesting in the Arctic Circle for almost 73 million years, newly discovered fossils reveal
A major collection of more than 50 bird fossils found in northern Alaska suggest some ancient ancestors of modern birds learned to either adapt to the harsh Arctic winter, or migrate south during the Mesozoic — the age of dinosaurs.
